Studies show that the average tub contains more bacteria than a toilet! And in one study, researchers found staph bacteria, a common cause of serious skin infections, in 26% of bathtubs tested! That was compared to just 6% of garbage cans! Bathtubs also have 10 times the bacteria in a dog’s food bowl! So, at least once a week, spray your tub with disinfecting cleaner, scrub, and rinse.
